Troubleshooting Measures for Common Issues in Medium-High Pressure Centrifugal Fans

Troubleshooting Measures for Common Issues in Medium-High Pressure Centrifugal FansMedium-high pressure centrifugal fans are widely used in industrial production and play a vital role in manufacturing processes. However, after a certain period of operation, unexpected situations may arise. These fans encounter numerous problems during operation. I have selected several representative issues for detailed explanation. I hope this proves useful to everyone. Many users encounter this situation: the air pressure of the medium-high pressure centrifugal fan reaches the standard value, but the air volume is extremely low. What could be the cause? In this case, consider the following three reasons. First, excessive dust and impurities in the surrounding environment. During operation, if the air within the fan's operating environment contains large amounts of dust and impurities, the unit's workload increases significantly. Naturally, gas output drops substantially, affecting normal operational efficiency. Therefore, it is essential to provide the machine with a clean operating environment. Second, the ductwork connected to the medium-to-high pressure centrifugal fan may be clogged. If the ducts become blocked, airflow through the exhaust outlet is restricted, reducing the volume of discharged air and increasing pressure. In this case, promptly clean the ductwork to clear the obstruction, which will resolve the issue. The third scenario involves damage to the medium-to-high pressure centrifugal fan unit itself. Common causes include worn impeller blades that fail to promote airflow effectively, or a malfunctioning motor. Operators must promptly replace the blades or purchase/install a new motor to restore normal operation of the medium-to-high pressure centrifugal fan and increase airflow.
